What is manual testing?Manual testing is a process of finding defects in the software manually. In this method, the testers will simulate end users to verify that all the features are working properly before software is released. All will be done manually so this method is really time-consuming. As it is done manually, it doesn’t require any knowledge of testing tool. Below are the stages of manual testing that a software will go through: Unit testing: Unit testing is the first stage in software testing. In this method, developer or tester uses the white box testing technique to test individual units and components of the software application to ensure that each unit of the software is working as expected. Integration testing: After unit testing, the units, components, and modules are integrated together and then integration testing is performed. The purpose of this testing is to validate the functionality and reliability of the modules after integrated. Black box testing technique is usually used at this stage, but in many cases, both Black and White testing method are combined together. System testing: In this stage, the entire system is completely integrated together to carry out system testing. Similarly, system testing is performed to ensure that the software is meeting its software requirements specifications (SRS). Black box testing is normally used at this stage. User acceptance testing: User acceptance testing is the final stage in software testing prior to release the product. After system testing, the software will be tested by actual users to make sure that the application has met all the requirements. If the software passes this stage, it means that end user has accepted it and it is ready to go live. What is automated testing?Automated testing is a method using an automation tool testing tool to write and execute test case suite on the software application, comparing the actual results to the expected behavior and creating test reports. Moreover, automation testing tool also provides record and playback feature which is especially useful for regression testing.When it comes to automation testing, it’s hard for testers to be good at it without programming skills. Automation testing is like development, so tools might require customization. But over time, automation testing tool has matured to simplify the process of testing. There are a lot of codeless automation testing tools in the market providing graphical environment so that testers can easily create test cases. Automation testing helps eliminate tasks that are too time-consuming and laborious to be performed manually, plus automated tests can be run repeatedly once they have been created. In other words, automation testing helps increase effectiveness and efficiency of software testing. For the small companies, it’s hard to adopt test automation as it’s too expensive and difficult. The initial investments are considerable but in the long run, automation testing can help reduce time to market and testing effort, thus saving money.
